Fraud can take place on a small scale (say credit card skimming) or a vast scale (when a rogue trader at an investment bank loses billions). This is a fascinating field of practice suited to those with a nose for forensic detail. Lawyers in private practice will almost certainly specialise in defence work, but the 'revolving door' to the regulatory community does enable a switch to prosecution work. Within a firm handling smaller fraud cases, there may be scope for advocacy but it is likely that clients will instruct a barrister to do this instead.
